The conventional method of feeding broilers, using high density diets has been found to be associated with increases in fatness and a number of metabolic disorders. The adverse effect of high density diets on the performance of broilers was found to be more pronounced under a tropical environment. Allowing broilers free access to feed using low density diets (quantitative nutrition) has been suggested as a strategy to improve the performance of the broilers within the prevailing environmental conditions in the tropics. A specific approach had been evaluated as suitable for reducing the available metabolisable energy (AME) intakes of the broiler and increasing feed intake. This involves diet dilution with high fibre feedstuffs to reduce the available metabolisable energy (AME) value of the diet.
